CAR-STARTER.

SPECIFICATION forming part of Letters Patent N o. 738,086, dated September 1, 1903.

Application iiled April 20, 1903. Serial No. 153,556. (No model.)

T0 all wtont it may concern:

Be it known that we, JOHN ROSS TROTT and SIMON HENRY SUTPHIN, citizens of the United States, residing at Yirden, in the county of Macoupin and State of Illinois, have invented new and useful Improvements in Car-Starters, of which the following' is a specification.

Our invention has relation to car-starters, and is more particularly designed as an iinproveinent on Letters Patent granted to us November 25, 1902, and numbered 714,623; and the same consists in the construction and arrangement of parts, as will be hereinafter described, and particularly pointed out in the claim.

In the accompanying drawings, Figure 1 is a side elevation of our apparatus. Fig. 2 is a top view of the rods, their guides, the shoe, and the lug at the opposite ends of the rods.

Referring to the drawings, the numerals 1 and 2 designate blocks which are spaced apart and arranged one in front of the other, the forward one of which has an inclined top surface provided with a pressure-head 9, operating in a socket-chamber S. On the upper surface of the block 1 is mounted a socketchamber 15, inA which operates a plunger 11. Secured to the two blocks 1 and 2 is a fluidchamber 5, communicating therewith and with the chambers S and 15. The forward block 2 is provided with sharp wedge-shaped grippers 1, which are adapted to coact with the upper surface of the rail to prevent the same from slipping during operation of the apparatus.

Mounted on the fluid-chamber 5 is an upright 11, having pivoted thereto an extension 12, which in turn has its upper end pivoted to the inner end of the lever 13, said upright and its extension serving to regulate and give force to Ithe lever 1:3 during the operation of the plunger 11, and said lever serving also to operate the shoe 24: by means of the rods 20, secured thereto.

The numeral 20, as shown in Fig. 2, designates two horizontal parallel bars arranged on opposite sides of the blocks 1 and 2, and 21 designates guides by which the blocks are retained on the rail, the upper part of guides 21 being so shaped as to form a tube or carrier through which rods 2O may be easily worked forward and backward,

2 designates cap-screws bymeans of which guides 21 are held securely in place.

28 Ydesignates the junction of the rods 20, at Ywhich point said rods 2O are attached to a shoe 24C, which is suitably shaped to the configuration of the periphery of the wheel and the tread of the rail. y

18 designates a cross-bar joining together the rear ends of rods 2O by suitably-adjusted nuts 19. n

The rearwardly-projecting lug 7 at its rear extremity is attached to upright 16, the upper end of said upright being pivotally connected with an angle-iron 17.

That the operation may be more fully understood we hereby give a detailed description of the different parts and their positions before operating. rlhe car starter being placed on the rail a short distance behind the car-wheel, lever 13 is raised to its highest point, and the same being attached to plunger 1e necessarily carries it to its highest elevation, this movement at the same time causing pressure-head 9 to recede to its lowest point. Vhen lever is elevated, angle-iron 17, being released from downward pressure from lever 1S, assumes a position parallel with upright 16, cross-har 1S resting against angleiron 17 at its lower end in its receded position. The shoe 2-t being in its rearward position is resting against front end of car-starter 2. The apparatus being now in proper position is pushed forward by means of lever 13 until convex bearing 10 of the pressure-head 0 engages rim of wheel. Leverl now being depressed, 11 is thereby at its lower extremity brought in forcible contact withfluid in chamber thereby necessarily forcing pressurehead Q upward andmovingcar forward. Lever 13 in its downward stroke is brought in Contact with upper top end of angle-iron 17. By this means the lower end of angle-iron 17, being forced forward, comes in contactwith cross-bar 18, forcing rod 20 forward and placing shoe 2-1 snugly in place under wheel. By raising lever and pushing car-starter forward the same operation may be repeated indefinitely.

Having described our invention, what we claim is- A car-starting apparatus comprisingblocks, a vfluid-chaniber secured between the same IOO and communicating therewith, ysocket-chamto operate the shoe and means secured to the ro bers in said bloc-ks, t plunger in one of said Huid-chamber and to the lever to not as a fulohamhers and a, pressure-head in the other Crum for the lever, substautiallyas speeied. chamber, bars on opposite sides of the blocks I TOEN ROSS TROTT 5 operatinp' in 0rudes secured thereto, a shoe 1 T 7 i 011 one erd ofothe rods, and a lug on the other i SIMGN HEB RX SUTPHIN' end thereof, 2L lever pvoted to the plunger lVtnesses:
